微小粒径钙钛矿锡基阻燃材料制备工艺研究
Research on the Preparation Process of Small Particle Size Perovskite Tin Based Flame Retardant Material
摘要
Abstract
In this paper,calcium stannate samples were prepared by different processes,and the phase structure,microscopic morphology,product purity and particle size distribution of the samples were tested.First,the XRD test results showed that there was no impurity peaks generation in the calcium stannate synthesized by the two processes,and the samples prepared in process A had good crystallinity;Second,The results of scan-ning electron microscopy(SEM)showed that the samples prepared by process A were more dispersed,more evenly distributed,and the particle size was smaller(200-700 nm);the results of particle size and purity test showed that the calcium stannate product prepared by process A has smaller particle size than that prepared by process B,and the purity of the pure product was 99.41%after calcination for 6 h,This indicated that the perovskite calcium stannate sample prepared by SnCl4·5H2 O had better crystal structure and microstructure under this process.The product index is good,is expected to show a better flame retardant performance.关键词
